Look upon every man, woman, and everyone as God. You cannot help anyone, you can only serve: serve the children of the Lord, serve the Lord Himself, if you have the privilege.
The key to your happiness is to own your slippers, own who you are, own how you look, own your family, own the talents you have, and own the ones you don't. If you keep saying your slippers aren't yours, then you'll die searching, you'll die bitter, always feeling you were promised more. Not only our actions, but also our omissions, become our destiny.
The leaders we revere and the businesses that last are generally not the result of a narrow pursuit of popularity or personal advancement, but of devotion to some bigger purpose. That's the hallmark of real success. The other trapping of success might be the by product of this larger mission, but it can't be the central thing.
Do not be too timid and squeamish about your actions. All life is an experiment. The more experiments you make the better. What if they are a little coarse and you may get your coat soiled or torn? What if you do fail, and get fairly rolled in the dirt once or twice? Up again, you shall never be so afraid of a tumble.
